Hi,
I have displayed the music list in a list view. The list is obtained from a website. I have done this using Arraylist. Now, i want to iterate the same program using custom lists and custom adapters instead of array list. The code i have written using array lists is...
public class MusicListActivity extends Activity {
MediaPlayer mp;
File mediaFile;
TextView tv;
TextView albumtext;
TextView artisttext;
ArrayList<String> al=new ArrayList<String>();
//ArrayList<String> al=new ArrayList<String>();
ArrayList<String> node=new ArrayList<String>();
ArrayList<String> filepath=new ArrayList<String>();
ArrayList<String> imgal=new ArrayList<String>();
ArrayList<String> album=new ArrayList<String>();
ArrayList<String> artist=new ArrayList<String>();
ListView lv;
Object[] webImgListObject;
String[] stringArray;
XMLRPCClient client;
String loginsess;
HashMap<?, ?> siteConn = null;
//ImageView im;
Bitmap img;
String s;
int d;
int j;
StreamingMediaPlayer sm;
int start=0;
Intent i;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.openadiuofile);
lv=(ListView)findViewById(R.id.list1);
al=getIntent().getStringArrayListExtra("titles");
//node=getIntent().getStringArrayListExtra("nodeid");
filepath=getIntent().getStringArrayListExtra("apath");
imgal=getIntent().getStringArrayListExtra("imgpath");
album=getIntent().getStringArrayListExtra("album");
artist=getIntent().getStringArrayListExtra("artist");
// ArrayAdapter<String> aa=new ArrayAdapter<String>(this,R.layout.row,R.id.text2,al);
//lv.setAdapter(aa);
try{
lv.setAdapter( new styleadapter(this,R.layout.row, R.id.text2,al));
}catch(Throwable e)
{
Log.e("openaudio error",""+e.toString());
goBlooey(e);
}
lv.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3){ j=1;
try{ d=arg2;
String filep=filepath.get(d);
String tit=al.get(d);
String image=imgal.get(d);
String singer=artist.get(d);
String movie=album.get(d);
sendpath(filep,tit,image,singer,movie);
// getpath(n);
}catch(Throwable t)
{
goBlooey(t);
}
}
});
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
if(j==0)
{i=new Intent(this,gorinkadashboard.class);
startActivity(i);}
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
j=0;
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode==KeyEvent.KEYCODE_SEARCH)
{
Log.i("go","go");
return true;
}
return(super.onKeyDown(keyCode, event));
}
public void sendpath(String n,String nn,String image,String singer,String movie)
{
Intent ii=new Intent(this,MusicPlayerActivity.class);
ii.putExtra("path",n);
ii.putExtra("titletxt",nn);
//ii.putStringArrayListExtra("playpath",filepath);
ii.putExtra("pos",d);
ii.putExtra("image",image);
ii.putStringArrayListExtra("imagepath",imgal);
ii.putStringArrayListExtra("filepath", filepath);
ii.putStringArrayListExtra("imgal", imgal);
ii.putExtra("movie" ,movie );
ii.putExtra("singer",singer);
ii.putStringArrayListExtra("album", album);
ii.putStringArrayListExtra("artist",artist);
ii.putStringArrayListExtra("tittlearray",al);
startActivity(ii);
}
class styleadapter extends ArrayAdapter<String>
{
Context context=null;
public styleadapter(Context context, int resource,
int textViewResourceId, List<String> objects) {
super(context, resource, textViewResourceId, objects);
this.context=context;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
final int i=position;
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
View v = inflater.inflate(R.layout.row, null);
tv=(TextView)v.findViewById(R.id.text2);
albumtext=(TextView)v.findViewById(R.id.text3);
artisttext=(TextView)v.findViewById(R.id.text1);
tv.setText(al.get(i));
albumtext.setText(album.get(i));
artisttext.setText(artist.get(i));
final ImageView im=(ImageView)v.findViewById(R.id.image);
s="http://www.gorinka.com/"+imgal.get(i);
// displyimg(s,v);
// new imageloader(s,im);
String imgPath=s;
AsyncImageLoaderv asyncImageLoaderv=new AsyncImageLoaderv();
Bitmap cachedImage = asyncImageLoaderv.loadDrawable(imgPath, new AsyncImageLoaderv.ImageCallback() {
public void imageLoaded(Bitmap imageDrawable, String imageUrl) {
im.setImageBitmap(imageDrawable);
}
});
im.setImageBitmap(cachedImage);
return v;
}
}
public class imageloader implements Runnable{
private String ss;
//private View v;
//private View v2;
private ImageView im;
public imageloader(String s, ImageView im) {
this.ss=s;
//this.v2=v2;
this.im=im;
Thread thread = new Thread(this);
thread.start();
}
public void run(){
try {
// URL url = new URL(ss);
// URLConnection conn = url.openConnection();
// conn.connect();
HttpGet httpRequest = null;
httpRequest = new HttpGet(ss);
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);
HttpEntity entity = response.getEntity();
BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(entity);
InputStream is = bufHttpEntity.getContent();
// BufferedInputStream bis = new BufferedInputStream(is);
Bitmap bm = BitmapFactory.decodeStream(is);
Log.d("img","img");
// bis.close();
is.close();
im.setImageBitmap(bm);
// im.forceLayout();
// v2.postInvalidate();
// v2.requestLayout();
} catch (Exception t) {
Log.e("bitmap url", "Exception in updateStatus()", t);
//goBlooey(t);
// throw new RuntimeException(t);
}
}
}
private void goBlooey(Throwable t) {
AlertDialog.Builder builder=new AlertDialog.Builder(this);
builder
.setTitle("Exception!")
.setMessage(t.toString())
.setPositiveButton("OK", null)
.show();
}
}
I have created the SongList.java, SongsAdapter.java and also SongsAdapterView.java. Their code is...
public class SongsList {
private String titleName;
private String movieName;
private String singerName;
private String imagePath;
private String mediaPath;
// Constructor for the SongsList class
public SongsList(String titleName, String movieName, String singerName,String imagePath,String mediaPath ) {
super();
this.titleName = titleName;
this.movieName = movieName;
this.singerName = singerName;
this.imagePath = imagePath;
this.mediaPath = mediaPath;
}
public String gettitleName()
{
return titleName;
}
public void settitleName(String titleName) {
this.titleName = titleName;
}
public String getmovieName()
{
return movieName;
}
public void setmovieName(String movieName) {
this.movieName = movieName;
}
public String getsingerName()
{
return singerName;
}
public void setsingerName(String singerName) {
this.singerName = singerName;
}
public String getimagePath()
{
return imagePath;
}
public void setimagePath(String imagePath) {
this.imagePath = imagePath;
}
public String getmediaPath()
{
return mediaPath;
}
public void setmediaPath(String mediaPath) {
this.mediaPath = mediaPath;
}
}
public class SongsAdapter extends BaseAdapter{
private Context context;
private List<SongsList> listSongs;
public SongsAdapter(Context context, List<SongsList> listPhonebook){
this.context = context;
this.listSongs = listSongs;
}
public int getCount() {
return listSongs.size();
}
public Object getItem(int position) {
return listSongs.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View view, ViewGroup viewGroup) {
SongsList entry = listSongs.get(position);
return new SongsAdapterView(context,entry);
}
}
public SongsAdapterView(Context context, SongsList entry) {
super(context);
this.setOrientation(VERTICAL);
this.setTag(entry);
// TODO Auto-generated constructor stub
View v = inflate(context, R.layout.row, null);
TextView tvTitle = (TextView)v.findViewById(R.id.text2);
tvTitle.setText(entry.gettitleName());
TextView tvMovie = (TextView)v.findViewById(R.id.text3);
tvTitle.setText(entry.getmovieName());
TextView tvSinger = (TextView)v.findViewById(R.id.text1);
tvTitle.setText(entry.getsingerName());
addView(v);
}
}
Can anyone please tell me how to display the list using custom lists and custom adapters using the code above???
